Several process technicians in the casting workshop were also at the receiver casting site. As the three receivers were poured one by one, the people talked together.

"Mr. Liu, do you think this precision casting of titanium alloy can be successful?"

"Well, it's hard to say, but I'm not the craftsman in charge of this titanium alloy receiver casting process, maybe it can succeed!"

"If this casting is successful, it would be amazing. This is the casting of a complex thin-walled titanium alloy receiver, which is very difficult. Looking at the entire country, it should be considered top-notch."

"Well, not only is the casting structure relatively complex, but the casting accuracy is very high, and the highest accuracy can reach about twenty threads."

Twenty silk!

Many craftsmen took a breath and looked shocked. In the past, the casting accuracy was generally thirty threads. Without thinking, the accuracy has been greatly improved.

Suddenly, many people were looking forward to it, and some of the technical workers on the scene were also looking forward to it. If the casting was successful, it means that the precision casting process has reached a new level.

Next to Li Tianfeng, Zeng Qinghai also looked serious. In fact, Zeng Qinghai was really a little worried, worried that the casting would fail.

Seeing that the pouring was successfully completed and nothing unusual, Zeng Qinghai was a little relieved. Seeing that the entire pouring was completed, Li Tianfeng just waited for the cooling and opening the mold, so Li Tianfeng waved his hand and said, "Mr. Zeng, we will come again in the afternoon."

Zeng Qinghai pointed out: "Boss, I don't know what will happen after the mold is opened in the afternoon. I hope the casting will be successful."

Li Tianfeng said: "If this type of highly difficult titanium alloy complex thin-walled receiver is successfully cast, it will be of great significance. In the future, we will be able to capture similar titanium alloy receivers."

The two of them walked out of the casting workshop as they spoke.

Outside the casting workshop, look into the distance along the avenue at the entrance of the workshop, and you can see the huge construction site in the distance. This is the second phase of Tianfeng Technology Company's project, which is a total of 1,000 acres, which is relatively huge.

The construction plan for this thousand acres was originally designed to be a very famous planning and design institute in China. The plan was very beautiful and scientific.

Now, many factories here are under construction, and some factories that were built earlier have basically completed the main construction, and the construction of these factories is coming to an end.

Zeng Qinghaidao: "Boss, if our second phase of the project is completed, our Tianfeng Technology Company will be completely renewed."

Li Tianfeng said: "After the second phase of the project is completed, our Tianfeng Technology Company will not only double its scale, but also increase its production capacity exponentially."

Zeng Qinghaidao: "Boss. As the turboshaft e engines begin to enter mass production, our monthly output of engines has exceeded 100 units, and the production pressure in each workshop in the first line is still relatively high."

Amazon's turboshaft e engine order is 800 units, and the delivery is completed within 12 months. 50 units are delivered every month in the first 6 months, and the remaining 500 units are delivered in the next 6 months.

The number of turboshaft e delivered in the first six months is relatively small, otherwise the production pressure of the first-line workshops will be even greater. However, even so, some production workshops have begun to work overtime.

Li Tianfeng said: "When our second phase of construction is completed and these factories are put into use, our production pressure will be greatly alleviated. In addition, we will also set up a special international industry and trade branch to be responsible for the processing of outsourced parts, such as Harry Pottery, Pratt & Whitney, e Factory, Jiufang Equipment Company and other companies.

International Industry and Trade Company will specialize in the parts processed by other companies, while each workshop specializes in the production of turboshaft d, turboshaft e engine parts, and subsequent turbofan engine parts.

The processing of the second batch of turbofan blades has been completed. Combined with the defects and shortcomings of the first batch of blades, the process parameters have been optimized and improved. According to the new process, the processing of the second batch of blades has been smooth and the progress is relatively fast.

Two or three of the second batch of blades have been inspected in the metallographic analysis room. Under the electron microscope, the metal structure, metal grains and other conditions can be clearly seen.

Xiao Liu was responsible for the inspection. Last time, Xiao Liu was also responsible for the inspection. This time he was very familiar with the road and seemed more skillful.

Metallurgy is normal!

After watching it, Xiao Liu was surprised. Ye Ji's metallographic structure seemed to be better than last time, very good.

Director Yang, who was next to him, accidentally saw the happy expression on Xiao Liu's face and couldn't help but ask: "Xiao Liu, how is the situation?"

Xiao Liu said: "Director Yang, the metallographic structure of these fan blades is very good, and the performance of the blades, especially the metal mechanical properties, must be very outstanding."

Director Yang was also happy, which shows that the titanium alloy material of this batch of blades is one point higher than the previous batch of fan blades. He couldn't help but say: "Xiao Liu, hurry up and check the welding bonding surface of the two halves."

"Yeah, I'll check it right away."

While agreeing, Xiao Liu began to check happily. Under the microscope, the welding bonding surface of the two halves of the blades was also clearly visible, including the metallic metallographic structure of this part.

The two halves are welded to the bonding surface, and the situation is very good. The two halves are combined very beautifully, and there are no defects, and there are no micro cracks, which is very perfect!

Xiao Liu was amazed, far from thinking that the two blades were welded so well, perfectly forming a whole, integrated into a fan blade of very high quality.

Very wonderful!

Tsk, it's so beautiful. Xiao Liu seemed to be a little immersed in it and never get tired of watching it. It was not until Director Yang next to him that Xiao Liu came to his senses.

"Xiao Liu, how is the situation!"

"Director Yang, very perfect, very beautiful! The two halves of the leaves are simply integrated without any defects. Director, come and take a look."

Upon hearing this, Director Yang also became interested, walked over, came to the microscope, and looked at it seriously. After looking at it, Director Yang felt a sense of relief and a sense of relief!

"That's great! This shows that our superplastic molding and connection processes are very successful, and the process parameters are also very scientific and reasonable."

Director Yang and Xiao Liu were feeling happy. Li Tianfeng brought Zeng Qinghai in. Seeing the appearance of the two, Li Tianfeng felt inexplicably lightened. A high-hanging heart slowly lowered. This time, Li Tianfeng came to the metallographic analysis room. Li Tianfeng came to see the metallographic analysis of the second batch of fan blades.

"Mr. Li, the result is very perfect. Come and take a look."

Upon hearing this, Li Tianfeng became interested, walked over quickly, looked at it in person, and after looking at it, Li Tianfeng said: "Mr. Zeng, you come and have a look."

Zeng Qinghai also came over and looked at it happily. After looking at it, Zeng Qinghai said happily: "Boss, we have succeeded. The two halves of the blades are perfectly combined. There are no defects in the welding bonding surface. I am so happy!"

Li Tianfeng also nodded happily: "Mr. Zeng, the super-plastic molding and connection process have been successful, and we have taken another solid step, one step closer to the successful development of this turbofan engine."

Fan blades, especially this wide-string hollow titanium alloy fan blade, are very important and are the key and important parts of the fan part. Now that the blade trial production is successful, everyone is unhappy.

Li Tianfeng felt a burst of joy and a burst of joy in his heart.

…………

In the afternoon.

The titanium alloy receiver that was poured in the morning has been cooled naturally and reached the temperature of mold opening. Several workers are opening the mold according to the process requirements and taking out the cooled titanium alloy receiver. On the site, several process technicians are also present, including the technical director of the casting workshop.

The three titanium alloy receivers were taken out one by one, and the receiver was still relatively warm. The workers carefully cleaned the inner and outer surfaces of the receiver, cleaned the receivers one by one with soft brushes, and then blew them with a wind gun to make the surfaces of the three receivers clean.

The three-piece receiver is not heavy because it is a titanium alloy thin-wall receiver. The receivers are placed on the inspection platform one by one to prepare for inspection.

The first is appearance inspection.

An experienced inspector began to carefully look at the appearance of the receiver. The same was true for several craft technicians next to him, surrounding one of the receivers.

"Wow, it's really beautifully cast!"

"Well, very beautiful, very exquisite!"

"It seems to be a little more beautiful and exquisite than the various titanium alloy receivers we cast before!"

"Yes, yes, look at how delicate the surface of this receiver is, without any roughness."

Several technicians looked happy when they looked at the receiver. They were all craftsmen, and there were also craftsmen in charge of the casting process of this receiver. It would be strange if the cast receiver was so beautiful and so exquisite.

Before casting, everyone was very worried about the failure of casting. Unexpectedly, after casting the receiver, it could reach such a level. Although the size is like, whether there are any internal casting defects, I don’t know these yet, but at least they look good, exquisite and beautiful.

This is extremely happy!

The inspector next to him was also carefully looking at a receiver. Seeing that it was so beautiful and the casting appearance was so good, he nodded secretly.

"Yeah, it's pretty good!"

Hu Dongxu, the technical director of the casting workshop next to him, also nodded, and was very happy. This exquisite appearance is good.
